Yes, it was just his nerves!!!! He is doing great.. thanks for the postive feedback.... I was worried at first, but I'm sure glad he got past that problem.
As he threw up shortly after he started Kindergarten it may be as simple as nerves ....how is he doing now ?
court1980 - vomiting in public situations is one of the signs of severe anxiety. You mentioned that your son was "shy" - another "sign" of anxiety. As always, your first step is to contact your family doctor re advice. You might wish to educate yourself on anxiety by googling terms such as "anxiety and school" or "behaviors of anxiety in children" or "anxiety disorders in children" or similar words/phrases.
If your family doctor is unable to help you, the ask for a referral to a medical mental health specialist with experience in anxiety issues as a child neurologist or child psychiatrist. Anxiety is a mental, emotional and physical disorder - very common - but with proper treatment, the prognosis is excellent. It does appear that your son will require "help" in learning how to manage and cope with his fears/anxieties. All the best .....
Did you find out what caused him to throw up, was he upset by something at school ..as he is new there he may gets used to it, something was a trigger .
I think he needs to see a counselor, and you need to have a close communication with the teacher and principal. If he's vomiting within the classroom, it needs to be addressed.
I don't think schools should have to deal with a child who vomits in the classroom - that's on the parents and the family to correct.
